Class DerivedStateAwareModelChangeListener

java.lang.Object

com._1c.g5.modeling.xtext.resource.DerivedStateAwareModelChangeListener

All Implemented Interfaces:

IModelChangeListener

public class DerivedStateAwareModelChangeListener
extends Object
implements IModelChangeListener

IModelChangeListener implementation aware of derived state computer for given resource.

This implementation handles model change events and if IDerivedStateComputer.isAffected(org.eclipse.emf.ecore.resource.Resource, org.eclipse.emf.common.notify.Notification) returns true, then it forces discard and install of derived state for given resource.

Method Detail

modelChanged

public void modelChanged(org.eclipse.emf.common.notify.Notification event)

Description copied from interface: IModelChangeListener

The source will invoce this method to announce changed resource. The event will never be null. However, it may contain an empty list of deltas.

Listeners are free to remove themselves from the sender of the event or add other listeners. However added listeners will not be informed about the current change.

This event fired synchronously.

Specified by:

modelChanged in interface IModelChangeListener

Parameters:

event - the fired event. Will never be null.
